Technical Field

[0001] The utility model relates to the technical field of lighting lamp beads, in particular to a light leakage-proof lamp bead. Background Art

[0002] As an emerging green, environmentally friendly and energy-saving light source, lamp beads are widely used in car lights, flashlights, lamps and other places.

[0003] A Chinese patent application CN202022987684.2 discloses a high-voltage LED lamp bead. The key points of its technical solution are: the utility model has a simple structure and does not need to change the original structure of the LED lamp bead, thereby increasing adaptability. It can be directly assembled on the fixing ring, and the pins on the LED lamp bead are pressed and fixed by the extrusion positioning mechanism. No welding is required, which facilitates subsequent disassembly and greatly increases replacement efficiency.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the light source of the lamp bead may be difficult to fully utilize, resulting in a waste of energy; when the staff uses the lamp bead body to emit light, the light generated by the lamp bead body diffuses around the lamp bead body, resulting in the objects that need to be illuminated by the lamp bead body not meeting the illumination brightness, thereby causing the problem of not meeting the staff's use needs; therefore, a light leakage-proof lamp bead is proposed to address the above problems. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that the object to be illuminated by the lamp bead body cannot meet the illumination brightness, thus failing to meet the use requirements of the staff, and proposes a light leakage-proof lamp bead.

[0007] The effect achieved by the above-mentioned components is: by setting up a focusing device, the light generated by the lamp bead body is gathered and prevented from being scattered, thereby preventing the light generated by the lamp bead body from diffusing around the lamp bead body when the staff illuminates the lamp bead body, resulting in the objects that need to be illuminated by the lamp bead body not meeting the illumination brightness, thereby causing the situation that the staff's use needs cannot be met, thereby improving the practicability of the device.

[0009] The effect achieved by the above components is: the focusing tube is fixed and limited, which prevents the focusing tube from being hit by external factors when the lamp bead body is in use, causing the focusing tube to drive the semicircular block to rotate in the semicircular frame, thereby causing the focusing tube to detach from the surface of the lamp bead body.

[0010] Preferably, one end of the fixing rod away from the fixing plate is fixedly connected to a limiting plate, and the size of the plug plate is adapted to the size of the plug hole of the connecting plate.

[0011] The effect achieved by the above components is: the limit plate limits the maximum sliding distance of the operating panel on the arc surface of the fixed rod, thereby preventing the operating panel from detaching from the arc surface of the fixed rod due to the small size of the operating panel and the difficulty of the staff in fully controlling their pulling force when pulling the operating panel.

[0012] Preferably, the arc surface of the fixing rod is sleeved with a first spring, and two ends of the first spring are fixedly connected to the fixing plate and the operating plate respectively.

[0015] The effect achieved by the above components is: by setting up a protective device, the connector is waterproofed, which prevents water from being directly splashed onto the surface of the connector when the lamp bead body is stored or idle, causing the connector to be stained with a small amount of water stains that are difficult to wipe dry, thereby causing a short circuit when the lamp bead body is used, thereby improving the protection of the device.

[0016] Preferably, a handle is fixedly connected to one end of the driving rod away from the protective cover, and the size of the protective cover is matched with the size of the connector.

[0017] The effect achieved by the above components is that the handle makes it convenient for the staff to operate the device, so that the staff can have a more suitable point of force.

[0018] Preferably, a positioning rod is fixedly connected to one side of the protective cover close to the driving rod, and the arc surface of the positioning rod is slidably connected to the support plate.

[0019] The effect achieved by the above components is that the positioning rod achieves the effect of limiting the protection cover from rotating along with the driving rod, so as to increase the sealing performance of the protection cover when protecting the connector.

[0020] In summary, the beneficial effects of the utility model are:

[0021] 1. In the utility model, by setting a focusing device, the effect of gathering and preventing the light generated by the lamp bead body is achieved, which prevents the light generated by the lamp bead body from diffusing around the lamp bead body when the staff emits light from the lamp bead body, resulting in the object that needs to be illuminated by the lamp bead body not meeting the illumination brightness, thereby causing the situation that the staff's use needs cannot be met, thereby improving the practicability of the device.

[0028] Reference Figure 1 As shown, the utility model provides a technical solution: an anti-light leakage lamp bead, comprising a lamp bead body 1, characterized in that: connectors 2 are installed on both sides of the lamp bead body 1, and a focusing device 3 is provided on the surface of the lamp bead body 1. By setting the focusing device 3, the light generated by the lamp bead body 1 is gathered and prevented from being scattered, which prevents the staff from illuminating the lamp bead body 1 with the light generated by the lamp bead body 1 diffusing around the lamp bead body 1, resulting in the objects that need to be irradiated by the lamp bead body 1 not being able to meet the irradiation brightness, thereby resulting in the situation that the staff's use requirements are not met, thereby improving the practicality of the device, and a protective device 4 is provided on the lower surface of the lamp bead body 1. By setting the protective device 4, the effect of waterproofing the connector 2 is achieved, which prevents the lamp bead body 1 from being directly splashed with water from the outside onto the surface of the connector 2 when the lamp bead body 1 is stored or idle, resulting in the connector 2 being stained with a small amount of water stains that are difficult to wipe dry, thereby causing a short circuit when the lamp bead body 1 is used, thereby improving the protection of the device.

[0029] The specific configuration and function of the focusing device 3 and the protective device 4 will be described in detail below.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the focusing device 3 includes two semicircular frames 301, the two semicircular frames 301 are fixedly connected to the surface of the lamp bead body 1, the surface of the lamp bead body 1 is slidably connected to two semicircular blocks 302, the side of the two semicircular blocks 302 close to each other is fixedly connected to a focusing tube 303, the focusing tube 303 is slidably connected to the surface of the lamp bead body 1, the inner surface of the focusing tube 303 is fixedly connected to a plurality of reflective stickers 304, the arc surface of the lamp bead body 1 is fixedly connected to a fixing plate 305, the surface of the fixing plate 305 is fixedly connected to a fixing rod 306, the arc surface of the fixing rod 306 is slidably connected to an operating plate 307, the side of the operating plate 307 close to the fixing plate 305 is fixedly connected to an insert plate 308, the arc surface of the focusing tube 303 The surface is fixedly connected with a connecting plate 309, and a socket is opened on the surface of the connecting plate 309. When the staff needs to use the focusing tube 303 to focus the lamp bead body 1, the focusing tube 303 is pressed, and the focusing tube 303 drives the semicircular block 302 to move until the semicircular block 302 fits the surface of the lamp bead body 1. At this time, the focusing tube 303 is rotated to make the focusing tube 303 rotate on the surface of the lamp bead body 1. At the same time, the focusing tube 303 drives the semicircular block 302 to rotate until the semicircular block 302 rotates into the semicircular frame 301. At this time, the operating plate 307 is pressed, and the operating plate 307 slides on the arc surface of the fixing rod 306. At the same time, the operating plate 307 drives the plugging plate 308 to move until the plugging plate 308 is inserted into the socket of the connecting plate 309. At this time, the focusing is achieved. The focusing tube 303 has a fixed and limited effect, which prevents the focusing tube 303 from being hit by the outside when the lamp bead body 1 is in use, causing the focusing tube 303 to drive the semicircular block 302 to rotate in the semicircular frame 301, thereby causing the focusing tube 303 to detach from the surface of the lamp bead body 1. The end of the fixing rod 306 away from the fixing plate 305 is fixedly connected to the limiting plate 310, and the size of the plug plate 308 is matched with the size of the plug hole of the connecting plate 309. When the staff pulls the operating plate 307, the operating plate 307 slides on the arc surface of the fixing rod 306. At this time, the limiting plate 310 has the effect of limiting the maximum sliding distance of the operating plate 307 on the arc surface of the fixing rod 306, thereby preventing the staff from pulling the operating plate 307 due to the operating The plate 307 is relatively small, and it is difficult for the staff to fully control their pulling force, resulting in the operating plate 307 being detached from the arc surface of the fixing rod 306. The arc surface of the fixing rod 306 is sleeved with a first spring 311, and the two ends of the first spring 311 are respectively fixedly connected to the fixing plate 305 and the operating plate 307. When the staff releases the operating plate 307, the rebound force of the first spring 311 drives the operating plate 307 to slide on the arc surface of the fixing rod 306. At the same time, the operating plate 307 drives the plug plate 308 to move until the plug plate 308 is inserted into the socket of the connecting plate 309. At this time, the first spring 311 improves the stability of the plug plate 308 when limiting the connecting plate 309, thereby improving the stability of the plug plate 308 when fixing the focusing tube 303.

[0031] Reference Figure 4 As shown, specifically, the protective device 4 includes a strip plate 41, which is slidably connected to the lower surface of the lamp bead body 1, and two support plates 42 are fixedly connected to the side of the strip plate 41 close to the lamp bead body 1. A driving rod 43 is inserted into the inner thread of the support plate 42, and one end of the driving rod 43 is rotatably connected to a protective cover 44, and the protective cover 44 is slidably connected to the surface of the strip plate 41. A handle 45 is fixedly connected to the end of the driving rod 43 away from the protective cover 44. The size of the protective cover 44 is adapted to the size of the connector 2. When the staff needs to rotate the driving rod 43, the driving rod 43 can be driven to move in the inner thread of the support plate 42 by rotating the handle 45. At this time The handle 45 makes it convenient for the staff to operate the device so that the staff can have a more suitable point of force. The protective cover 44 is fixedly connected to the side close to the driving rod 43 with a positioning rod 46. The arc surface of the positioning rod 46 is slidably connected to the support plate 42. When the staff turns the handle 45, the handle 45 drives the driving rod 43 to move in the inner thread of the support plate 42, the driving rod 43 drives the protective cover 44 to move, and the protective cover 44 drives the positioning rod 46 to slide in the support plate 42. At this time, the positioning rod 46 limits the protective cover 44 from rotating with the driving rod 43, so as to increase the sealing of the protective cover 44 when protecting the connector 2.

[0032] Working principle: when the staff needs to focus and prevent the lamp bead body 1 from scattering, they pull the operating plate 307 to make the operating plate 307 slide on the arc surface of the fixing rod 306, the first spring 311 is stretched, and the operating plate 307 drives the plug plate 308 to move until the plug plate 308 no longer blocks the movement of the connecting plate 309. At this time, the focusing tube 303 is pressed, and the focusing tube 303 drives the semicircular block 302 to move until the semicircular block 302 fits the surface of the lamp bead body 1. At this time, the focusing tube 303 is rotated to make the focusing tube 303 rotate on the surface of the lamp bead body 1. At the same time, the focusing tube 303 drives the semicircular block 302 to rotate until the semicircular block 302 rotates into the semicircular frame 301. At this time, the operating plate 307 is released, and the return of the first spring 311 The elastic force drives the operating plate 307 to slide on the arc surface of the fixing rod 306, and at the same time, the operating plate 307 drives the plug plate 308 to move until the plug plate 308 is inserted into the socket of the connecting plate 309. At this time, the light emitted by the lamp bead body 1 will be limited to the range of the focusing tube 303, and at the same time, the reflective sticker 304 reflects the light until the light of the lamp bead body 1 is gathered. At this time, the effect of gathering and preventing the light generated by the lamp bead body 1 is achieved, which avoids the light generated by the lamp bead body 1 from diffusing around the lamp bead body 1 when the staff emits light, resulting in the objects that need to be illuminated by the lamp bead body 1 cannot meet the illumination brightness, thereby causing the situation that the staff's use needs cannot be met, thereby improving the practicability of the device.

[0033] When the staff needs to protect the connector 2, the lamp bead body 1 is placed on the surface of the strip plate 41 and the handle 45 is turned at the same time. The handle 45 drives the driving rod 43 to move in the inner thread of the support plate 42, and the driving rod 43 drives the protective cover 44 to move. The protective cover 44 drives the positioning rod 46 to slide in the support plate 42 until the protective cover 44 covers the connector 2. At this time, the connector 2 is waterproofed, which prevents the lamp bead body 1 from being directly splashed with water from the outside onto the surface of the connector 2 when it is stored or idle, causing the connector 2 to be stained with a small amount of water stains that are difficult to wipe dry, thereby causing a short circuit when the lamp bead body 1 is used, thereby improving the protection of the device.
